Robert Shelton, Blain Mamiya, Rebecca Weber, Deborah Rush Walker, Cynthia B. This report summarizes one of the invited papers for the ConfChem online conference on Mathematics in Undergraduate Chemistry Instruction, held from October 23 to November 27, 2017, and hosted by the ACS DivCHED Committee on Computers in Chemical Education (CCCE). It is hoped that these methods can help motivate students to gain greater intuitive and conceptual insight into the chemistry through solving quantitative problems, and to become more fluent in expressing science in the language of math. Students’ evaluations of this pedagogical approach are also discussed. Examples of such problems and their pencil-and-paper solution methods are presented in the areas of chemical equilibrium, acid–base reactions, buffers, and titrations. Multiple-choice exams incorporating problems of this type, in which calculators were not allowed, were also administered. When doing such problems in class, the instructor can efficiently interleave reminders of basic algebraic methods to simplify expressions, to work with common and natural logs, and to estimate results to one or two significant figures. The present paper describes some methods subsequently used to enhance students’ math fluency through solving numerical problems using pencil-and-paper math, without the use of a calculator.

You should spend a good deal of your online time working these problems they are a good source of questions for chemistry quizzes and for hour exams. Once you have attempted answering the problem, you can check your work with the Show Answer button. In general, you will receive a unique problem every time you work one of these. The Tutorial link takes you to a set of algorithmic tutorials and exercises that deal with many of the central concepts in the course.These are "answers only"… please see the text for the complete questions. The answers to the problems at the end of the chapters in the text are collected in the chapter answer link.These are images from the text and again, they are designed for online viewing and review, but not for printing. The textbook link will take you to an online version of the text, Introductory Chemistry Online.These are useful for review or as content in the "Flipped Classroom". The microtutorials are short movies that focus on a single topic (Elements & Isotopes, Significant Figures, etc.).Many of the questions on these slides resemble actual archived exam questions. The exam review slides are from the PowerPoint slides that we typically go through prior to each of the exams.These images are not designed for printing! The lecture slides are images taken from the PowerPoint slides and they are arranged in a "stack" that allows easy viewing in order to review the content.The links shown on the left will take you to the available content areas in the Introductory Chemistry site.
